Abstract: The climatic conditions are the main determining genetical elements of ice phenomena and processes in the rivers, reservoirs and channels. The probabilistic concept of the winter phenomena with their statistical processing is an important factor for the evaluation of the technico-economical and social significance of winter phenomena. By a suitable interpretation of the results a good base for predictions of the winter regime under stationary conditions, but also for cases of non-stationarity due to human activities can be given. Especially the phenomena with multiannual periodicity, such as are also ice phenomena in the moderate zone /e. g. of Central Europe/, require for probabilistic evaluation long series of observation. In Czechoslovakia with a very meteorological and hydrological service, there exist very favorable conditions for these solutions /meteorological data in Prague-Klementinum since 1776 and hydrological data for river Labe at Decin since 1851/. The application of these long observation series for the understanding and characteristics of the winter regime phenomena and processes of water bodies is the main topic of the paper.
